Centralised systems use chillers which are basically giant a c units but they work slightly differently because of their size.
Condensers transfer heat to the air or to a water or glycol fluid and remove it from the air that will be circulated.
All building need air conditioning.
A condenser removes heat and is on the hot side of the air conditioner.
Lower chiller set point when mixing occurs to maintain a constant temperature to the system.
A slightly positive pressure to reduce outside air infiltration.
